PROBLEM TO BE SOLVED: To supply a generator with heat from the arm without lowering temperature by arranging inside a back lid a heat collector plate formed of a material having higher heat conductivity than the back lid and bringing a heat receiver of a generator into contact with a heat collector plate. SOLUTION: The heat collector plate 7 formed of a material such as aluminum, copper, etc., is coupled and fixed to a contact member 5A with a high heat conductivity on the inner surface (movement 1 side surface) of a back lid 5 formed with metal such as Ti, Ti alloy, stainless steel, etc., having a relatively low heat conductivity. Then, a heat reception part 6a of a thermoelectric type generator 6 is contacted to a heat collector plate 7 and a radiation part 6b is fixed to the heat conduction part 3a of a radiation upper shell 3 via a heat conduction plate 8. Since the heat collector plate 7 forms a part in contact with the heat reception part 6a in a thick part 7a, heat tends to stagnate to maintain the temperature high, the heat transmitted from the arm to the back lid 5 is effectively collected inner direction and conducted to the heat reception part 6a side as maintained at a high temperature. |
